BICYCLE-BELL.

SPECIFICATION forming part of Letters Patent No. 617,220, dated January3, 1899.

Application filed December 23, 1897. Serial No. 663,111. (ModelJ To allwhom it may concern.-

Be it known that I, ABNER W. BARTON, of East Hampton, in the county ofMiddlesex and State of Connecticut, have invented a new Improvement inBicycle-Bells; and I do hereby declare the following, when taken inconnection with the accompanying drawings and the letters of referencemarked thereon, to be a full, clear, and exact description of the same,and which said drawings constitute part of this specification, andrepresent, in

Figure 1, a top View of a double bell embodying my invention, with theouter bell re,- moved; Fig. 2, a sectional view on the line a l) of Fig.1; Fig. 3, broken views of the inner end of the central post and thecenter of the inner bell. Figs. 4, 5, and 6 illustrate the operation ofthe bell; Fig. 7, a plan view of a modified form of hammer-carrier andhammer-lever; Fig. 8, a side view of this modified construction.

This invention relates to an improvement in bicycle-bells, andparticularly to that class in which two gongs are employed, the objectof the invention being to constructa bicyclebell in which either asingle stroke may be given, a double stroke, or a qu-adruple stroke; andit consists in connecting the end of the operating-lever with ahammer-lever and adjusting the throw of the operating-lever, whereby thenumber of strokes is regulated, and in certain details of constructionand combinations of parts, as will be hereinafter described, andparticularly recited in the claims.

While the mechanism is particularly intended for double bells, it isequally applicable for single bells. With two bells the inner bell Awill preferably be secured to the upper clamp member B by the inner endof the central post 0, which post will be flattened at its inner end ato set into a groove (1. in the center of the bell, whereby the rotationof the bell on the post will be prevented. Upon the post within theinner bell is fixed a plate D, formed with an upright arm E, the purposeof which will hereinafter appear. Proj ecting upward from this plate isa lever-post F, on which is mounted the operating-lever G, whichprojects through a notch b in the edge of the bell A in the usualmanner. This lever is actuated in one direction by a spring H, whichengages with one side of the lever and with the plate D. On one side ofthis lever is a lug g, through which extends a screw I, arranged so asto strike the arm E as the lever is turned and so that the movement ofthe lever will be regulated by the projection of the screw beyond thesaid lug. The inner end of the lever G is connected with a hammer-leverJ by a segmental link K, the said hammer-lever J being hung upon a pivotd, projecting upward from the said plate D. This hammer-lever extendsacross the bell and between arms 6 f of a hammer-carrier L, which ismounted upon a stud h, extending upward from the said plate I). Securedto the hammer-carrier by an arm M is the hammer N, which is segmental inshape and reversely beveled at its opposite ends, so that one end atwill strike the lower bell and the opposite end n the upper bell A,which is mounted upon the upper end of the post 0. A spring 0 isconnected with the under side of the hammer-carrier L at m, a pointcentrally between the arms 6 f, and with the central post 0, thetendency of said spring being to move the said carrier against themovement of the hammer-lever, but as the carrier turns and brings thespring to bear in the opposite direction the spring will operate toforce the hammer to strike the bell, thus giving a sharp decisivestroke. The movement of the lever G by the thumb-piece G causes the linkK to move the hammer-lever J so as to throw its end J to one side, asshown in broken lines,-Fig. 1, and as this end J extends between theends 6 f of the hammer-carrier that carrier is turned against the actionof. the spring 0 and so as to swing the hammer N.

. The position of equilibrium of spring 0 is found when 00 (its point ofconnection with the hammer-carrier L) lies in the straight line betweenthe posts 0 and h. In this position the spring 0 is under compression,but cannot exert its energy, as it is resisted by the posts 0 and h.When 0: is forced on either side of the straight line, the spring thenrelaxes and carries its hammer-carrier L to one side or the other.

If a single stroke is desired, the screw I will be turned outward, so asto strike the arm E just as 00 reaches the straight line. As a: is notpermitted to pass this line the ham mercarrier L is not swung on itspivot sufficiently to permit the spring o to relax and carry the hammerN on the other side of the line, and the end it consequently does notcontact the bell A.

If a double stroke is desired, the screw I will be turned slightlyinward, so as not to contact with the projection E until the actuationof the lever G has caused a; to approach and pass the point ofequilibrium and the end it of the hammer, under the energy ot the spring0, to contact the bell A. The lever G is then returned to its initialposition under the energy of the spring II, and the end To contacts thebell A, which respective positions are shown in full and dotted lines inFig. 4.

If a quadruple stroke is required, the screw will be withdrawn, so thatthe lever may be turned to such an extent as to cause the lever-arm tobe first thrown outward to the position shown in broken lines in Fig. 4,so that the end at of the hammer will strike the bell A. Then thecontinued movement of the lever to the position shown in Fig. 5 returnsthe lever-arm to its former position, whereby the end at is allowed tostrike the bell A. Then as the lever is released and returns to itsnormal position the end at of the hammer again strikes the bell A andthen returns, so that the end it again strikes the bell A, a doublestroke being given in each direction of the operating-lever.

The object of forming the hammer-carrier with the arms e f is that thesearms may be bent toward or from the hammer-lever, so as to adjust thethrow of the hammer; but instead of constructing the hammer-carrier inthis Way it may consist of a coiled spring P, mounted on the post it,one end of the spring, Q, supporting the hammer N and the other end, B,ext-ending inward and turned up through a washer S and a rectangularopening T in the end of the hammer-lever J, as shown in Figs. 7 and 8.With this construction a spring 0, corresponding to the spring 0, beforedescribed, will connect the arm R of the spring with the central post 0.Otherwise the mechanism will be as before constructed, and the operationis substantially the same. By limiting the movement of theoperating-lever either a single, double, or quadruple stroke may beproduced.

In addition to adjusting the throw of the hammer by bending the ends ofthe hammercarrier the movement of the bell mechanism may be adjusted bybending the link K so as to lengthen or shorten it, and thereby increaseor diminish the throw of the hammerlever.

It is apparent that the adjusting-screw I might be mounted in the arm E,so as to stand in the path of the lug g and so as to limit the movementof the operating-lever in the same manner as above described.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-
